Just wanted to say how much I appreciate your channel and you taking the time to break everything down. I have a 5th grader, 2nd grader, and kinder. We have utilized your channel a lot, especially when it comes to newer style math that I was not taught. I have told all my parent friends about you! Thank you for making math easy AND showing different examples. In a time where books are kept in the classroom (vs. issued books), your channel has saved the day more than once! :D
